To all whom it may concern:

Be it known thatwe, WILLIAM MILLS and canning or, in other words, the improper application of the can tops, and instead 'of destroying the cans and allowing the food to go to waste, it is the aim torenew the tops of the oans by first removing the top of the condemned can, as" may belaccompli'shed by. the apparatus of the co-pending application filed the ninth day of Se tem-' ills.-

ber, 1920-, in the names of 'William and Clark Percy, Serial No. 409,274, 'allowed March 26,1921, and after removing the top of the condemned can, it is the aim of the present invention to refi'ange the can so that anew top may be applied Another object of the invention is topro vide a can flanging member having a marginal; curved surface terminating inan upper outwardly curved annular portion,

k r of the can will engage the upper outwardly" whereby when the marginal curved "portion is forced Within the can, the marginal edge curved annular part of the flan'ging device and cause the wall of the canto flange outwardly. 4 1 V Stillj'another object is the provision of a machine wherein means is aflorded for forcing the flanging device within the can.

A further object embodies the provision of a flanging device having openings to er, mit the level of the liquid or the contents of the can to rise when the flanging device is forced within the can.

While the design and construction at present illustrated and set forth is deemed pref-c erable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right-to these changes is claimed, pro= scope of what is claimed. v

The lnventlon comprises further features Vided they are comprehended within the and combination of parts, as will be-herei-n after set forth, shown in the drawings and claimed@ ln'the drawingsr p c t m rsr -f Patented Feb, 21, 1922.

wardly. The plunger will move axially concentric with the can which is held on the base of the frame 1 in any suitable manner and as the plunger approaches the can, the flanging device will telescope within the can and cause the outward spreading or the wall of the can.

The flanging device consists of a cylindrical body 22 having at its lower portion a circular flange 23. Extending downwardly from the flange 23 is an annular-rib 2a, the marginal outer surface of which is curved inwardly and downwardly, as indicated at 25, so that the annular rib may telescope the can 26. The curved surface of the rib of the fianging device terminates at its upper portion in an outwardly curved annular portion 27. In other Words, the upper part of the curvature 25 flares outwardly, acting to cause the marginal edgeof the wall 01 the can to flare outwardly as the flanging device telescopes the can. It is, to be noted that when the top of the can has been severed so as to reflange the can, the upper level of the fluid or contents of the can will be veryclose to the marginal edge of the can, hence it is the aim to provide the flanging device with openings 28 to permit the fluid or contents of the can to rise instead ofoozing from the can as the fianging device telescopes the same. This also prevents the can from overflowin as the Hanging device telescopes the can. otter the can has been reflanged, a new top may be applied by any suitable can topping machine. The operating lever 20 may be manually operated or automatically operated. v

The invention having been set forth, what is claimed as new and useful is:

1. In a can flanging machine, a frame, meansfor supporting a can to be flanged on the frame, a plunger mounted for vertical movement on the frame and axially concen 2. In a can hanging machine, thecombinatlon with a can fiangmg device, of a plunger ca "rying said device, tensioning means for the plunger, a support in which said plunger is mounted for vertical movement, an oscillatory lever; pivoted on the support and loosely connected to said plunger, a member mounted for reciprocating movement in said support, movable means connecting the sup-v port and one end of said lever, and a link connecting the movable means at a point substantially intermediate where said means connects the lever and the support, and in turn connected to the reciprocating member, whereby an oscillatory movement may be imparted to said lever, thereby moving the plunger against its tensioning means.

3. In a can Hanging machine,the combination with a can hanging device, of a plunger carrying said device, tensioning means for the plunger, a support inwhich said plunger ismounted for vertical movement,,an oscillatory lever pivoted on the support and loosely connected to said plunger, a member mounted for reciprocating movement in said support, oscillatory movable elements pivotally united, one connected to the oscillatory lever, the other to the support, and means connected to said elements where they are pivotally united, and in turn to said reciproeating member, whereby oscillatory movement may be imparted to said lever, thereby moving the plunger against tensioning means.

In testimony whereof we hereunto aflix our signatures.
